This is the Grimmspeed OEM Style Throttle Body Gasket. This particular intake gasket has been made using quality paper materials to ensure a proper seal between the throttle body and the intake manifold. If you have a vacuum issue or an unusual idle, then your throttle body gasket could be the culprit. With that being said, save yourself the expense of making a trip to the stealership, and get one on order from RallySport Direct.
